Abstract
The invention discloses a fine-turning sucking sheet device for a single-layer capacitor bare chip separation tester, which comprises a sucking head mounting base sliding sleeve. Two sides of the sucking head mounting base sliding sleeve are symmetrically provided with guiding buffer mechanisms which are connected with a guiding mounting rack. A screw hole on the middle part of the guiding mounting rack is connected with a fine turning mechanism. The fine turning mechanism is integrated with a sucking device which is mounted in the sucking head mounting base sliding sleeve. A spacing mechanism and a vacuum air source interface are arranged between the sucking device and the sucking head mounting base sliding sleeve. The fine-turning sucking sheet device for the single-layer capacitor bare chip separation tester reduces over-flush and shake in sucking bare chips by a sucking nozzle because of overlarge inertia in high-speed sucking process, and settles the quality problems of scratch, damage, crack, etc. in sucking process for the bare chip particles. Furthermore sucking deviation which possibly occurs and separation testing result error are prevented.
